I want to find the particular file name in particular directory in ruby.

I tried the following Dir.glob()

file = Dir.glob("/home/prakash/Desktop/*.uploaded")

output:

/home/prakash/Desktop/abc.uploaded

But I just want only the file name in output. I don't want file name with fully path.

So how can I do this?

In Ruby, there is a file class.

File.basename("/home/prakash/Desktop/abc.uploaded")

The above will return abc.uploaded

Since I'm not sure if you want the extention or not, you can remove it using

File.basename("/home/prakash/Desktop/abc.uploaded", ".uploaded")

The above will return abc

Or you could perform a string manipulation

'/home/prakash/Desktop/abc.uploaded'.split('\\').last

  • Actually I don't know the file name on particular directory, I just know the extension of that file i.e. .uploaded, by using this extension i want to find the file name only without full path in prefix Commented Apr 29, 2014 at 7:38
  • So, the name abc could be anything? If so, the code above will work! Commented Apr 29, 2014 at 7:40
  • yes name abc could be anything. In you code you have given the fully path upto fine name to "File.basename()" class. But i don't know the file name, I know only the file extension then how can i do? Commented Apr 29, 2014 at 7:44
  • I'm sorry, I'm still a little lost - why don't you know the file name? If Dir.glob(... is returning the full path, then you do know it? Commented Apr 29, 2014 at 7:47

I got easy way to find only file name without full path:

file = Dir.glob("/file/path/*.uploaded").join(" ") filename = file.split('/').last

And it's working great for me
